MPPT 40A 12V24V LCD Display Solar Controller Automatic Identification Off-Grid System Controller 1. Adopt DCDC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge controllers, MPPT can increase the output efficiency of solar panels by 5% to 30% (the rate of increase in output is affected by the attributes of solar panels, ambient temperature and lighting conditions). 2. LCD liquid crystal display, USB output, the product can charge various lithium batteries, activate lithium batteries, etc. 3. DSP processor architecture ensures the high speed and performance of the controller 4. MPPT efficiency is greater than 99%, and peak conversion efficiency is greater than 98% 5. 12V24V automatic recognition 6. PV input: 100V 7. Four-stage charging mode 8.
